Added support for BlueChart g2 and g2 Vision version 11.5.

Added support for Portuguese fishing areas.

Added support for dolphin buoys.

Added support for using built-in map update SD cards.

Fixed a potential shutdown when animated tides are enabled.

Fixed a rare issue where the unit may not be able to achieve a GPS fix after a power cycle.

Corrected the Fishing and Navigation Chart's Tracks control to turn the tracks off/on.

Updated the Russian translation for 'Gain.'

Changes made from version 5.20 to 5.30:

Improved depth tracking performance.

Changed the active track log scanning to display the date and time the point was recorded instead of the position.

Added support for displaying the compass tape on the Sonar pages.

Corrected how waypoint names display on maps when using a non 1252 codepage.

Corrected the AIS rate of turn value that was not using the correct sign of the value.

When the AIS alarm is set to off, the 'Remove Lost Target' message will not display and the lost target will automatically be removed after 2 minutes.

Removed the depth line control from the flasher menu.

Changes made from version 5.10 to 5.20:

Added the ability to turn off the AIS dangerous target alarm. When the alarm is set to off, dangerous targets will still display on charts, but the alarm banner that allows acknowledgement of a dangerous target will not be displayed. Unacknowledged dangerous AIS targets will turn red and blink on the chart even if the AIS dangerous target alarm is turned off.

Added an automatic light sector control which determines the best zoom levels to draw light sectors.

Added support for transferring waypoints, tracks, and routes to/from MapSource. This support was removed in the previous release.

Potentially dangerous points along auto guidance paths will be outlined in red. After the auto guidance calculation completes, a message will appear if there are potentially unsafe areas along the path.

Improved Mariner's Eye 3d operation under slow speeds

Changed the nature of seabed areas to label the area instead of drawing a circle and label.

Fixed an issue where AIS targets with status of moored or anchored were showing up as lost prematurely.

Updated the symbol highlighting on the chart to use the correct symbol size.

Added the blue and black direction lines for orthogonal photo points.

Fixed an issue where Mariner's Eye 3d safe depth wasn't correct the first time you went to that view.

Fixed a bug where auto guidance lines can ignore the safety buffer on the first leg of the route.

Changes made from version 5.00 to 5.10:

Improved chart cartography presentation by reducing clutter.

Added support for displaying the compass tape on the Navigation and Fishing Charts.

Fixed a potential issue on the 3D page when displaying the backlight adjustment page.

Reduced the sonar bottom acquisition time in deep water.

Changes made from version 4.50 to 5.00:

Numerous rearrangements of menus, configurations, and adjustments to place most-used features in easy to access locations.

Made the Back button smarter to minimize the number of key presses required to exit commonly used features.

Changed the appearance of UI lists and allowed paging by using the -/+ keys.

Changed the symbols and colors to be closer to international standards.

AIS vessels are only filtered from the map by distance from the boat. The user can set up the range of interest or choose to show all AIS vessels up to a maximum of 100 vessels.

Added standard 'select and activate' interface for AIS. User can choose which targets to track with a larger symbol and heading/COG indications. All other AIS vessels display in a smaller symbol to minimize clutter.

Use a solid line for AIS vessel heading and a dashed line for course over ground.

Added user-controlled trails for AIS and DSC vessels.

Added connecting legs over shallow areas at the beginning and end of the path. This allows the boater to auto guide to a shore-based service. The unit will sound an alarm when the boat approaches the shallow leg.

Added a control for shore-line proximity tolerance which allows the user to choose tighter margins for passage through narrow channels or set a larger distance margin from the shoreline.

When following Auto guidance added a navigation option to recalculate Auto guidance to the current destination from the boat's current position.

Changes made from version 4.40 to 4.50:

Added warning for recalled g2 and g2 vision maps to not be used for navigation.

Changes made from version 4.30 to 4.40:

Added support for safety contour for enhanced g2 vision cartography.

Fixed rare shutdown while viewing specific chart locations.

Changes made from version 4.20 to 4.30:

Improved reliability of NMEA0183 output timing.

Changes made from version 4.10 to 4.20:

Added the option to configure the distance from a turn at which the system will transition to the next leg of a route.

Fixed issue where Mariner's Eye 3D may draw the water surface of a lake well below surrounding land when the scene contains only partial 3D information.

Fixed issue where a world base map would to be drawn instead of an available supplemental map when viewing an area near that supplemental map's border.

Fixed issue that may apply a weather warning to an area that is not under a warning in addition to the correct warning area.

Added support for the Arabic language.

Changes made from version 4.00 to 4.10:

Added the ability to configure the level of detail shown by the base map.

Modified to display all AIS targets on the charts by default, and added a menu item to only show the 5 closest AIS targets.

Dynamically scale fuel rate and fuel economy digital gauges.

Added G2 Vision Card information to the System Information Page

Added a 'Route Bar' control under 'Navigation Bar Setup', which toggles the display of additional route specific data.

Changed arrival alarm to trigger on arrival at 'Destination' or 'Destination and Turns' based on user's preference.

Added an option to create a route from a list of existing user waypoints.

Performing a Go To will now draw the desired track lane from the origin to the destination for those who wish to use Go To for following a specific course with minimum cross track error. The lane center line will still 'float' with the vessel for those who wish to navigate by bearing only. Routes can still be used to create navigation lanes with a fixed center line.

Added Offset Navigation which allows navigation based on a fixed distance from the original route. This is useful for trolling a precise distance from regulatory fishing boundaries.

Changed route creation on navigation and fishing charts to no longer require selecting 'Add Turn' for the last point if the pointer is moved away from the last 'Add Turn' position. When 'Done' is pressed, the location of the pointer will be the last route waypoint.

After saving a route created on the navigation or fishing charts, the user will be presented with the route review page so they can easily change the name at that time.
